    Participation and Decision Making: A Three-person Power-to-take Experiment

    It is often conjectured that participatory decision making may increase acceptance even of unfavorable decisions. The present paper tests this conjecture in a three-person power-to-take game. Two takers decide which fraction of the responder's endowment to transfer to themselves; the responder decides which part of the endowment to destroy. Thus, the responder can punish greedy takers, but only at a cost to herself. We modify the game by letting the responder participate in takers' transfer decision and consider the effect of participation on the destruction rate. We nd that participation matters. Responders destroy more if they (1) had no opportunity to participate in the decision making process and (2) are confronted with highly unfavorable outcomes. This participation eect is highly signicant for those responders (the majority) who show negative reciprocity (i.e., destroy more when takers are greedier).fairness, participatory decision making, power-to-take game, procedural fairness, reciprocity

    Sulphur in the Sculptor dwarf spheroidal galaxy - Including NLTE corrections

    In Galactic halo stars, sulphur has been shown to behave like other α\alpha-elements, but until now, no comprehensive studies have been done on this element in stars of other galaxies. Here, we use high-resolution ESO VLT/FLAMES/GIRAFFE spectra to determine sulphur abundances for 85 stars in the Sculptor dwarf spheroidal galaxy, covering the metallicity range −2.5≤[Fe/H]≤−0.8-2.5\leq \text{[Fe/H]} \leq-0.8. The abundances are derived from the S~I triplet at 9213, 9228, and 9238~\AA. These lines have been shown to be sensitive to departure from local thermodynamic equilibrium, i.e. NLTE effects. Therefore, we present new NLTE corrections for a grid of stellar parameters covering those of the target stars. The NLTE-corrected sulphur abundances in Sculptor show the same behaviour as other α\alpha-elements in that galaxy (such as Mg, Si, and Ca). At lower metallicities ([Fe/H]≲−2\text{[Fe/H]}\lesssim-2) the abundances are consistent with a plateau at [S/Fe]≈+0.16\text{[S/Fe]}\approx+0.16, similar to what is observed in the Galactic halo, [S/Fe]≈+0.2\text{[S/Fe]}\approx+0.2. With increasing [Fe/H], the [S/Fe] ratio declines, reaching negative values at [Fe/H]≳−1.5\text{[Fe/H]}\gtrsim-1.5. The sample also shows an increase in [S/Mg] with [Fe/H], most probably because of enrichment from Type Ia supernovae.Comment: 9 pages, 11 figures, 2 tables + 3 online tables, accepted in A&

    The privacy and control paradoxes in the context of smartphone apps

    Get PDF
    This research examines how various factors, such as the degree of e-privacy concerns and control over data access permissions, can influence a user's intention to install a smartphone app. We conducted two survey-based experiments with 441 participants. In each experiment, we manipulated the degree of control over the number and type of data access permissions granted to different fictional apps. In Study 1, participants were informed about the set of permissions the apps required. In Study 2, participants indicated which individual permissions they were willing to grant to the apps. In both experiments, we assessed the level of e-privacy concerns, perceived app importance, and the intention to install the apps. The results suggest that the type of app plays a central role in determining both the perceived benefit of installing the app and the level of e-privacy concerns. The intention to install an app is more strongly associated with perceived app importance than with e-privacy concerns (especially when app importance is high, and users have explicit control over which specific data access permissions they want to grant). The implications of these results are discussed regarding psychological factors involved in app installation decision-making process and the importance of promoting data protection by design

    Beyond greed: why armed groups tax

    Get PDF
    Based on a review of the diverse practices of how armed groups tax, we highlight that a full account of why armed groups tax needs to go beyond revenue motivations, to also engage with explanations related to ideology, legitimacy, institution building, legibility and control of populations, and the performance of public authority. This article builds on two distinct literatures, on armed groups and on taxation, to provide the first systematic exploration of the motivations of armed group taxation. We problematize common approaches toward armed group taxation and state-building, and outline key questions of a new research agenda

    Impulsive Social Influence Increases Impulsive Choices on a Temporal Discounting Task in Young Adults

    Get PDF
    Adolescents and young adults who affiliate with friends who engage in impulsive behavior are more likely to engage in impulsive behaviors themselves, and those who associate with prosocial (i.e. more prudent, future oriented) peers are more likely to engage in prosocial behavior. However, it is difficult to disentangle the contribution of peer influence vs. peer selection (i.e., whether individuals choose friends with similar traits) when interpreting social behaviors. In this study, we combined a novel social manipulation with a well-validated delay discounting task assessing impulsive behavior to create a social influence delay discounting task, in which participants were exposed to both impulsive (smaller, sooner or SS payment) and non-impulsive (larger, later or LL payment) choices from their peers. Young adults in this sample, n = 51, aged 18–25 had a higher rate of SS choices after exposure to impulsive peer influence than after exposure to non-impulsive peer influence. Interestingly, in highly susceptible individuals, the rate of non-impulsive choices did not increase after exposure to non-impulsive influence. There was a positive correlation between self-reported suggestibility and degree of peer influence on SS choices. These results suggest that, in young adults, SS choices appear to be influenced by the choices of same-aged peers, especially for individuals who are highly susceptible to influence
